  1. Walcott Quarry Vauxia gracilenta

    Six years ago I got the chance to visit the Walcott Quarry (see my longer post on this adventure in fossil trips) and while there I found this specimen of Vauxia gracilenta. Ever since I've wanted to make it part of my collection somehow, so this year for my birthday I decided to have a life reconstruction commissioned. Having seen the other fantastically detailed Cambrian models produced by @thorst, I asked him if he would be willing to reconstruct and 3D print the sponge. I drew an interpretation of the fossil and in no time he had it completed. A huge thank you for helping me make this possible. The level of detail in the model is incredible and you can clearly tell side by side that It's the same Vauxia that I found back in 2015. As soon a I have a proper fossil shelf it will have pride of place. Benton

  3. The Burgess Shale

    I’ve decided to take a break from dissertation writing and write up something else instead, one of the greatest fossil hunts I’ve been on, my trip to the Burgess Shale. Its been a little while since I got to go but here is the story as I remember it. I’ll write this up in a few parts since I took a lot of pictures and I’m going through and editing them as I go. Part 1: Going on an Adventure A little bit of background to start off. When I was younger (around 12 I think) I got the opportunity to go to the Smithsonian Museum of Natural History in Washington DC. Of all of the displays my favourite was a small board under glass with a half a dozen or so small dark slabs of shale, the museums display of the fossils of the Burgess Shale. I can’t remember if there actually was a Pikaia on display but I distinctly remember the Pikaia and when it came time to exit through the gift shop I went the book which had the closest looking thing on the cover. That book, needless to say, was Stephan Jay Gould’s ‘Wonderful Life’, a book which was admittedly a little above my reading level at the time but one that I was enthralled with nonetheless. I knew that one day I had to go see where they came from for myself. Fast forward to five years ago now, I had finished high school a few months previously and was one week away from starting university. For my graduation present I had been given tickets for a guided tour, my father and I were going, I was going to get to see the Walcott Quarry in the Burgess Shale. The whole trip was going to take three days, my father’s car (a beaten up red Ford Windstar which we weren’t sure was going to survive the trip) was packed was packed with tents, a small amount of other camping gear, my trusty blue backpack, and the requisite 5lb bag of trail mix and we set off on our way since the driving would take the better part of the first day. The folks at the border were a little suspicious when we told them we were going to Banff for only two days but after a half an hour or so of checking over the car we were allowed on our way again into Canada. After a few hours we started to get into the Rockies. Growing up in western Washington I’m used to big mountains but while the Cascades were large these were different. I took a few pictures out the car window, the sharp treeless peaks of some almost looked a little like teeth. After a long day’s drive we reached our campsite, just a few miles away from the parking lot where the tour would start the next day and set up camp. The next morning we were up with the sun. Our tour group consisted of about 8 of us in total, my father and I and a handful of others, mostly retired petroleum geologists. Just a few minutes up the trail and the scenery was already breath-taking with a waterfall thundering over the nearby rock face. Soon we had properly left civilisation behind and after about an hour or so of hiking, stopped at the edge of a crystal clear glacial melt water lake where the ranger went over a little about geologic time, using the ever popular calendar analogy (that humans have been around only for a few hours on the last day of the year compared to the age of the rocks we were going to see). The hiking became tougher as the incline increased, through the forest. I’d been on a fair number of hikes during my many years with scouts but I was definitely out of practice compared with the rest of the group, mostly septuagenarians, who seemed to make it up the trail like they were part mountain goat. After another little while there was a sign on the side of the trail and even though the surrounding mountains were shaded by the trees I knew we were getting closer. We stopped briefly to go over the regulations of the area, there is of course no civilian collecting in the Burgess Shale. The ranger also explained how rare the soft bodied preservation present was and passed around a map dotted with the locations of all the spots on the globe with Burgess Shale type preservation. I quickly took a picture in case I was ever nearby another one before we started on our way again. Continued in Part 2 . . .
  4. Hi everyone Last Thursday I went to visit the Royal Belgian Institute of Natural Sciences in Brussels as a little pre-birthday trip. I have visited this museum several times in the past few years, but this time I took my camera with me and thought it might be fun to do a photo tour of the museum for this forum Beware, this will be quite a big topic that might take a few days to complete as I took nearly 750 photo's in the museum (a lot will have to be sorted out though due to blurry quality, photo's of only name tags and doubles) as I wanted to show pretty much all fossil displays Especially the Hall of the Dinosaurs, the hall of the Mosasaurs & The Hall of Evolution will be quite complete tours Starting off with some snapshots of the hall of the minerals.

  5. Burgess Shale Still Has Fossils

    I think this is a bait and switch article. It starts off by telling you about the Burgess shale then transitions into explaining why we are going extinct too. I didn't learn anything new from reading it though. Anyway there are pictures. Of trilobites. https://www.washingtonpost.com/outlook/2019/12/06/ghosts-future/?arc404=true

  15. Fossils from Norway, Fossil ID.

    Hello guys and girls, I'm new here :-) Could you help me identify these fossils. They are all from my local city of Porsgrunn, Norway. I gathered these over the cause of a few days due to construction work, so I saved them before the whole area is buried under tons of rubble. The first fossil (1-2) around the size of a finger, the "branch" was much longer before I broke it lose, around half a meter. Image 3-5 is the one I am most curious about, could it be a trace fossil of some sort. It's embedded in the shale, some of the lines are 0,5 cm deep. From what I know Image 6 is most likely a Ragusa coral, and Image 7 is probably Stromatolites. The last fossil looks like it fell out of a geode at some point. :-) Most of the local fossils here in Porsgrunn can usually be dated to the Ordovician or early Silurian and they are relatively small in size. Porsgrunn in Telemark is a part of the Oslo Geological Field in Norway, which is a part of the Burgess Shale. The fossils in the Oslo Geological Field can be dated to around the Precambrian era to late Silurian. Thanks :-)
  16. Anomalocaridid Fossils?

    Anyone here have any Anomalocarididae fossils? I do realize that if anyone did they most likely wouldn't be on this site but just wanted to know. I also realize that they are extremely rare but that I've seen things on here comparable when speaking about rarity. (Kinzers Formation PA has confirmed - anomalocaris pennsylvanica.) Thanks;
  17. Cambrian Tectonic Plates

    Anyone have any information on tectonic activity during the Cambrian Period? I am writing a report on tectonic activity on Earth and am going to use the Cambrian to explain the location of the Burgess Shale and Chengjiang formations. So far I have a good idea of what I am doing, just wanted some input from others. I'll reference anyone that responds. Thanks.

  19. Hyolith finds place on the tree of life

    "In the past, hyoliths have been interpreted as being related to molluscs, which are common today and include squid, clams and snails. The new research suggests the animals are in fact more closely related to a different group of shell-bearing organisms, known as lophophorata, which includes brachipods (lamp shells), among others." http://www.bbc.com/news/science-environment-38585325

    QUOTE "As the oldest direct evidence of a creature caring for its offspring, the discovery adds another piece to our understanding of brood care practices during the Cambrian Explosion, a period of rapid evolutionary development when most major animal groups appear in the fossil record," said Jean-Bernard Caron, curator of invertebrate palaeontology at the Royal Ontario Museum and associate professor in the Departments of Earth Sciences and Ecology & Evolutionary Biology at the University of Toronto."
